Systemd auto start

Yes, you can start and stop servers gracefully and automatically by creating the Systemd scripts from Myst by following the steps below.

1. Prerequisites

  • oracle user has access to create directories:

    • /u01/app/oracle/bin

    • /u01/app/oracle/admin/shared/systemd

2. Add Myst Global Variable

The scripts use WebLogic userconfig and userkey files to authenticate to the NodeManager and AdminServer. Add these properties so the Myst scripts can generate the files without a prompt.

  1. Go to Platform Blueprint > Global Variables

  2. Add the global variable:

myst.system.properties=-Dweblogic.management.confirmKeyfileCreation=true

3. Configure Myst Custom Actions

Create plain text files in the Myst custom action.

Configure RHEL

  1. Create systemd unit file

    vi /etc/systemd/system/ofmw.service

    [Unit]
Description=Oracle Fusion Middleware control for NM, AS, MS, and OHS
After=syslog.target network.target cloud-final.service

[Service]
Type=oneshot
WorkingDirectory=/u01/app/oracle/admin/shared/systemd
ExecStart=/u01/app/oracle/admin/shared/systemd/ofmw-systemd-control-wrapper.sh "start"
ExecStop=/u01/app/oracle/admin/shared/systemd/ofmw-systemd-control-wrapper.sh "stop"
User=oracle
Group=oracle
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

  2. Initialise ofmw service

    systemctl enable ofmw
systemctl daemon-reload
systemctl status ofmw

  3. Start or stop ofmw service

    systemctl start ofmw
systemctl stop ofmw

  4. To view ofmw service's log

    journalctl -u ofmw.service

  5. Remove cloud-final.service from the unit file if you are not using AWS.

Scripts

Myst Custom Action ofmw-systemd-create-ofmw-properties creates:

  1. /u01/app/oracle/bin/ofmw-systemd-control-wrapper.sh

  2. /u01/app/oracle/bin/ofmw-systemd-control.py

  3. /u01/app/oracle/bin/ofmw.properties

Systemd script's workflow:

  1. ofmw.service -> ofmw-systemd-control-wrapper.sh

  2. ofmw-systemd-control-wrapper.sh -> ofmw-systemd-control.py

  3. ofmw-systemd-control.py -> Start/Stop NodeManager / AdminServer / Managed Server / HTTP Server

What are ofmw.properties and systemd.properties?

ofmw.properties

This file is generated from the Myst Custom Action ofmw-systemd-create-ofmw-properties.

The contents of the file are for the shell and jython scripts to determine how to start the NodeManager and its associated server(s).

adminUrl=host_as.mystsoftware.internal:7001

systemd.properties

The Myst Custom Action ofmw-systemd-create-ofmw-properties generates this file if it does not exist. Generally this file should be generated by the Linux environment on instance creation.

The contents helps the systemd OFMW startup scripts determine which node the script is running on by using the nodemanager's listen address.
